Aside from its low boiling point it is one of the most reacitve metals and will explode on contact with water and corrode in the air pretty instantainously. Its also very soft (and of low density). Uranium is a much better choice, its harder, denser (armor piercing shells are tipped with depleted uranium byproducts from nuclear refinement processess) and has a much longer half life, so is much more likely to be found lying about. (I suspect the slow burning and low-explosive reactions treebore had were due to using old cesium samples that had thick oxide layers or still had alot of petrolium on the surface (cesium is stored under oil to prevent exposure to air or moisture). The classical experiment with cesium is to drop a pellet in a bowl sized beaker of water, the beaker pretty much always "explodes" (shatters) from the reaction)As for the medical side, gamma-radiation easily penetrates human flesh and bone, though there is minimal absorbtion which is proportional to the density of the tissues, but at very high exposures enough is absorbed to do damage. The absorbed radiation causes radical ion formation within the cells, the body has natural radical scavengers but if the radicals are formed in very close vacinity to DNA then the DNA of cellc can be damaged, its the damage to the DNA that leads to various cancers. For this sort of exposue a Fort save is pretty reasonable <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f61b.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":P" title="Stick out tongue    :P"  data-smilie="7"data-shortname=":P" />At super etreme exposure so much of you Bodies DNA is attacked that your metabolic pathways fail and you stop functioning (ie breathing). If the armor is glowing.. the players probably died when they got within about 100foot of it. Of course, it is a game so the other option is to make the item out of madeupium and just not worry about any of this. <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":)" title="Smile    :)"  data-smilie="1"data-shortname=":)" />MajereA decent link here<a href="http://www.mii.org/Minerals/photocesium.html" target="_blank">http://www.mii.org/Minerals/photocesium.html</a></blockquote>
